I have a set of mesh cubes, 2 smallish & one medium. I love them, especially when flying when your bag could get opened by security. I also have some flannel shoe bags. They are also nice for keeping DH's shirts nice when he travels on business. The medium bag is just the size of the shirt after I fold it with my folding board. They seem to stay much neater that way than layered in the suitcase. I don't always use all of them, but the three I have fit quite neatly into my roll-aboard suitcase with room for a pair of shoes & a ziplock for my swimsuit & one for my liquids. (I think mine are Rick Steves, maybe discontinued. DH has some of the really light nylon/mesh ones.) Bonus, we can tell them apart. When we go on long trips we each carry a set of clothes for each other, in case one suitcase gets delayed or lost.
